WlNDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 394,008, dated December4, 1883.

Application filed July 24, 1888.

To (tZZ whom it may concern.-

Be it known that l, LOUIS ()PPENHEU'I, residing in the eity, eounty, andState of New York, have invented eertain new and useful Improvements inWindowSashes; and I do hereby declare that the l'ollowing is a full andexact deseription thereot', reference beinghad to the aeeom'ianyingdrawings, and to the leti ters of .reterel'iee marked thereon,making a part of this s ileeitieation, in whieh Figure 1 is an elevationin perspeetive of g a window titted with hinged sashes embodying myinvention, with the lower sash swung inward; Fig. 2, a similar viewshowing the upper sash lowered and both sashes swun inward; and Fig. 3,a detached view, in perspective, of a portion of one side of the casing,illustrating the slotted parting-strip and hinged stiopstrip.

Similar letters indieate like parts in all of the figures.

The objeet of my invention is to provide,

by direet simple means, for the ready opening of hinged wimlow-sashesconnt'erbalanced by weights and otherwise adapted in the enstomarymanner to be raised and lowered in p the casing.

It consists in the eombinatitm, with the ordinary eouuterbalaneedwimlow-sashes p.iv-.

oted upon a vertical. pivot-rod fixed at one edge of each sash upon oneside of the middle of its thielmess by hinge-plates secured to the topand bottoniot' the sash and formed with a lateral eye adapted to embracethe pivot-rod, ot atransversely-slotted partingstrip to engage pins inthe free lateral edge of the upper sash and a hinged stop-strip toengage the free lateral edge of the lower sash.

In the aeeoinpanying drawings, A represents the easing ot a window ofordinary form and construction, l-i its upper sash, and C its lowersash. The sashes B and are fitted to move up and down in the casingA inthe customary manner, and are eounterl)alanced by the usual weights, 1)I), attached to one edge thereof by eords E E, earri ed over thefrictionpulleys ll 1 to depend and work in the vertieal box formed inthe easing to reeeive them. In all these partieulars the sashes may beformed and titted in the usual manner, for

my invention may be readily applied, with Serial No. 280,907- (No model)1 but slight ehanges, to the eustomaryforms of t windmv-sashes now inuse.

1 To carry out my invention vertical iron rods G G are seeured parallelwith and adjacent. to that side of the window-easing in l whiehtheweights are placed, and in line with or just outside of the inner faceof eaeh sash B and so as to be out of line with or in front of avertical plane passing eentrally through the thiekness of the sash andinside of the proximate lateral edge of the sash when it is in its placein the easing. These upright. pivot-rods Gr G are each made fast to theeasing at top and bottom, but are otherwise tree for their entirelength.

I'Iinge-plates ll ll, formed with a suitable eye to embrace the rod G,and with a body adapted to be readily secured to the top and bottom. ofthe sash, as shown, or to its inner faee, are fitted upon eaeh rod G andG and made fast to the top and bottom of the sash, so as to hinge thesash upon the rod without interfering with its ordinary tree up or downmovement in the easing.

The opposite or tree lateral edge of the lower sash, is guided in itsvertieal movements by the customary sttm-strip I; but this strip ishinged to the casing to permit it to open out, so as to allow the edgeof the sash to turn outward from the easing when it is desired to swingthe sash open, as shown in the d rawin The tree lateral edge of theupper sash is eo'nlin ed and guided in its vertical movements as thesash is lowered or raised by means of pins .1 J, (see Fig. 3,) projecting therefrom into the longitiulinal guiding groove or reeess formed, asusual, by the parting-st rip K of the easing, and this parting-st rip isnotched or transversely slotted at suitable points (see at m in Fig. El)to permit the pins J .l to pass through it when it is desired to swingthe upper sash inward, as shown in Fig. 2.

In the use of the windowthus titted oreonstructed, both the upper andlower sashes are free to move up and down, being counterbalaneed by theweights 1) I), applied to one edge thereol, to operate in the usualmanner. At the same time either sash may be swung inward as a door.

To swing open the lower sash, the hinged stop-strip I is opened, so asto release the free side edge of the sash, as shown in Fig. 1. The sashmay then be turned upon its hinges II II Without interfering with theoperation of the sash-cord E and weight D, by which it iscounterbalanced. To swing open the upper sash, B, it is only necessaryto drop it until its retaining-pins J J are in register with thetransverse slots or notches m in the partingstrip K, whereupon it may befreely swung out upon its hinges. After being thus opened either sashmay still be raised or lowered, as illustrated in Fig. 2, its verticalmovements being guided by the plVOl l'Qd G to which it is hinged.

I am aware that window-sashes have heretofore been hinged at one edgeupon vertical rods, upon which they are free to be raised and lowered,and hence I do not claim, broadly, this feature of my invention.

My improvement relates specially to the peculiar novel devices wherebythe sashes may be swung upon their hinges when desired without removingthe stop and parting strips from the casing.

I claim as my invention 1. The combination, with a window-casing and asash mounted both to move up and down in said casing and to swingtherein of pins fitted in the free lateral edge of the sash, and a stripengaging said pins to confine the sash and having transverse slots toregister with the pins and thereby permit a swinging movement of thesash, substantially in the manner and for the purpose herein set forth.

2. The combination, substantially as set forth, of the windm casing, thesashes mounted to move up and down and to swing therein, the transversely-slotted parting-strip, the hinged stop-strip, and the pins inthe lateral edge of the upper sash adapted to register with the slots inthe parting-strip, substantially in the manner and for the purposeherein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LOUIS -OPPENHEIM.
